Lindalana, I think the quality of compost varies also depending on what it was made of, and whether there is unfinished material like wood or straw still present, not necessary for contamination to play a role.
I found myself in the same boat with poor quality compost this year. It was not contaminated in any way, I made it myself, but it was made mainly out of just sods and weeds and straw. There was quite a lot of unrotted straw still in it, but I thought it will help to aerate the soil overall and encourage the worms. But when I saw that fruit were not getting larger, I got concerned and did as you did, add some dried hen manure to help the situation.
